Belowthe line is a plan view of a section of the tile holder of feed thechains are free one pt where or box. they pass around idler sprockets 16which 1 is a box, sometimes called a feed boX, may be employed ifdesired for taking up open at top and bottom, in which one or slack, andat their free points, as for in more stacks of tile are placed. It isusually stance at 17, the two chains may be pulled apart so as to freepins 12 from sockets 11 and so remove cross-bars 13 for purposes ofreadjustment. In order to adjust the crossbars a good many more sockets11 may be provided on the chains than the number of bars usuallyemployed requires so that various spacings of the bars may readily beobtained. The feed belt 8 is driven in the direction of the arrow (inthe opposite direction to that of brushing apron at) by any suitablemeans.

Suppose the brushing apron at and feed belt 8 to be in motion and theparts to be in the position shown in Fig. 1. The stack of tile 3 restsupon apron 4: and since the apron is moving to the left as seen in thefigure, the ends of the tile are urged against the left hand end ofbox 1. The cross-bar 13 just to the left of the box moves with the beltand encounters the left end of the lowest tile in the stack which isbelow and free from the box. The continued movement of the cross-barcarries the lower tile with it, against the direction of movement ofapron at. The outer surface of the apron during this movement brushesthe lower surface of the tile, effectively removing dust and dirttherefrom. As the lower tile moves to the right those above it in thestack also move in the same direction and approach the right hand end ofbox 1. lVhen the right hand ends of the tiles encounter the end of thebox the upper tiles cease to move and the lower one is pulled from underthe stack. After the left hand or rear end of the moving tile @L. As therear end of the moving tile approaches the forward end of the box theother tile assume approximately the position shown in Fig. at. Vereapron 4 or other support provided for the tile stationary the tile wouldhave a tendency to remain in the position shown in Fig. et; that is thelowest tile in the stack would in many cases not drop-clear of the box,and proper feeding would be difficult or impossible. By reason of aprona moving toward the left, however, as soon as the weight of the stackrests upon it the stack commences to move again toward the left so thatit is carried away from the rear end of the box; the rear end of themoving tile shortly thereafter passes away from the box and the rearends of the stack drop so that the tile in the stack resume horizontalpositions with the lower surface of the lower tile flat upon apron 4:.Further movement of the apron carries the stack into contact with thefront end of the box and the operation is repeated indefinitely, eachcross-bar 13 carrying a tile before it.

It is to be understood that while only one stack of tile has beenreferred to, if several stacks are placed in the box the cross-bars willremove several tile at a time instead of one, and that the actions ofthe several stacks will be the same as that of the stack described.

The length of the box, as shown in Figs. 1 and 2, is somewhatexaggerated. The length of the box may be considerably varied inrelation to the length of the tile, but in any event it should exceedthe length of the tile sufficiently to permit the apron 4 to free thestack after the removal of each successive tile in the manner described.

Gross-bars 13 may be spaced apart longitudinally of belt 8 a sufficientdistance so that after the removal of a tile and the stack hasencountered the rear end of the box, apron at may move a considerabledistance and by contact with the lower tile brush it considerably beforethe approaching crossbar engages the tile. By another arrangement only aslightly greater distance may be provided between the cross-bars thanthe length of the tile and the brushing efiect of the apron may beexercised upon the tile principally during the time the tile is beingpositively moved by the cross-bar against the direction of movement ofthe apron.

Various other modified adjustments or are rangements may be made, but itis not thought necessary to further describe them.

Adjacent to the forward spool 5, supporting apron 4, are mountedrevolubly two pinch rolls 18 which conveniently have a covering offlexible or yielding material such for instance as soft rubber. Theserolls are revolubly mounted and adjustable to accommodate differentthicknesses of tile, and'they are driven by any suitable means in thedirection shown by the arrows. They are set with their adjacent facessomewhat nearer together than the thickness of the tile which are to befed, so that they squeeze the tile and positively carry it in thefeeding direction. 19 are two other pinch rolls, similar to 18, placedsomewhat to the rear thereof. Between the two sets of pinch rolls aretwo cylindrical brushes 20, one above and one below the line of feed.These brushes are revoluble and are mounted adjustably so that they maybe moved up or down in relation to the feed line.

20 represents devices for adjusting the brushes and rolls.

The brushes are rotated by any suitable means in the direction of thearrows or against the direction of movement of the tile. To the rear ofpinch rolls 19 a second or rear brushing apron 21 is carried on spools22 and driven in the direction of the arrow or oppositely to the feedingdirection by any suitable means. The'upper surface of apron 21 is insubstantially the same plane as that of apron 4: and apron 21 may be ofmaterial as apron e or may vary in racteristics as has already beenpointed in relation to the latter apron.
